How adorable are these tiny incense holders shaped like homes with a chimney? They’re one of the more recent designs from Mamoru Fukui and Daimon Kanno, the design duo who, together, form product design office A4.

The mini-structures, which are available for 545 yen, are upcycled from scrap wood leftover from the furniture design process, rendering each on unique. They range in size from 10mm (small) to 50mm (large).
